1.What is solar radiation?
Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy. Basically it means how much sun-light shining down on us.
2.How does Solar water heater works?
Solar water heater relies on warm water rising, a phenomenon known as natural convection, to circulate water through the evacuated glass tube collector and to the tank. Hot water storage tank is located above the absorber evacuated glass tubes. As water in the absorber heats, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the absorber, thus causing circulation throughout the system.
3.Can the Solar water heater heat water to a high enough temperature?
Yes, in sunny days Solar water heater can bring water to boiling point.
4.What happens if the Solar Collector panels are damaged or broken?
Firstly, panels are very tough and unbreakable, but if the worst should happen,the tempered glass cover will never break into pieces or hurt people, the glass cover can be replaced very easily.
5.Is Solar water heater a viable alternative to electricity?
Yes, Solar water heater System is an alternative to gas or electricity boosted geysers in some areas. Averaged over a year, a normal sized Solar water heater System can provide 80% to 100% of a household's hot water needs. . The hot water system can easily be added the electric backup heating stick so hot water is guaranteed regardless of sunlight levels.
6.How long will it take to recoup my investment?
Sungood solar water heaters are much more affordable than many other hot water heaters. For a household of 4, the price of a full system may not be too much more than a new electric or gas boosted geysers. Depending on your location (solar levels) and current hot water usage the annual electricity or gas saving will differ. However in a normal household that spends 35% of its electricity bill on hot water heating, the full cost of the purchase may be recouped as quickly as 2-3 years in reduced bills. You will definitely make considerable savings during the rest life of the Solar water heaters
7.Can Solar water heater be use in cold conditions?
Yes, Solar water heater can be used in temperatures as low as -20?C, although performance is reduced in such extreme conditions but Good heat output is still achieved in bad weather conditions as long as there is sunlight.
8.Will water be heated on a cloudy day?
Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature. This system will be automated with the existing electric geyser, so you don't have to worry about running out of hot water on a rainy day.
9.Are Evacuated Glass Tubes affected by frost?
No. The Solar water heater has been tested to minus 20?C and works extremely efficiently in cold climates.
10.Can I use Solar water heater with my existing Hot water System?
Normally yes. Simple retrofit valves can often be used to allow Solar water heater to connect to your existing geyser; the hot water system can easily be connected.
11.How can I be sure of the quality and performance of your products?
The range of Solar water heaters meet the rigorous tests set by the relevant industry standards and are made from the high quality components backed by generous warranties. At the end of the day, the quality and reliability of our products and the service we provide as a customer is best demonstrated by our customers. We receive regular praise from customers.
12.Who will install the Solar water heater at my roof?
The Solar water heater system should be fitted by an authorized and registered plumber who will ensure it is positioned correctly.
13.What maintenance of the Solar water heater is required?
Under normal circumstances no maintenance of the system is required. Due to the shape of the tubes regular rainfall and wind should keep the tubes clean. Should a tube even be broken it should be replaced. This, however, is an inexpensive and easy job. Any "handy" person can install a new tube.
14.Will the Solar water heater be a fire hazard during hot, dry weather?
No. The Solar water heating components are all high temperature rated and non-flammable so even during strong sunlight, the system will not catch a light or give off any sparks. The majority of our solar water heater's components are stainless steel, aluminum and glass.
15.Can Solar water heater be used for a large scale hot water production?
Yes. Solar water heater can be connected in series or parallel to provide large scale hot water production for a commercial setting such as a school, hotel or office building. There is really no limit to the size of the system, however collectors must be installed in banks of no more than 150 tubes (in series), otherwise the water may boil.
16.Can I heat my swimming pool using a Solar Geyser?
Solar water heater Collectors are high temperature collectors, and are therefore ideal for spas, as the volume of water is small and temperature requirements high. For swimming pools, however, the volume of water is large and the temperature rise required is only several degrees. The cost of heating a pool using evacuated glass tube collectors (for domestic purposes) may be prohibitively high. For large scale swimming pools, however, Solar water heater collectors may be an extremely viable supplement to gas or electricity.
17.Evacuated glass tube collectors VS. Flat plate collectors?
The flat plate solar collector is more popular in the market today,both types of solar collector are good in heating performance.
1. Flat plate solar collector has tough metal casing and basin which will never break, on the other hand, it heats the water by metal tubing directly and it's more efficiency, zero maintenance required.
2. The vacuum tube heats water through copper pipe indirectly,and the glass tube may be broken during a strorm or hail.
3. The Flat plate solar collector is visually better than the vacuum tube collector. The dark colored flat plate on the roof looks like a skylight.
18.How long does it take to install my Solar Geyser?
Installation is easy. Because Solar water heaters are lightweight, modular and include comprehensive installation instructions, you can expect an average installation to take 2-5 hours, depending on if you are retrofitting an existing home or new home and how experienced and knowledgeable the plumber is.
19.Are Solar water heaters expensive?
No. In the long term, a Solar water heater can save you up to 80% of your household's electricity or gas expenses and over a 20 year period is considerably cheaper than buying a straight electric or gas geyser due to the much lower running costs of a Solar water heating system.
20.How many people will the Solar water heater service?
There are several types and sizes of Solar water heaters available depending on the number of bathrooms and people living in the home. There are systems to suit every home.
21.How does using solar help the environment?
Using solar and other forms of renewable energy reduces reliance on fossil fuels for energy production, thus directly reducing CO2 emissions. CO2 emissions contribute to global warming, an environmental issue which is now of great concern. The average household can reduce CO2 emissions by as much as 20% by installing a Solar water heating system.
